I think im a dinosaur?

I like to stomp around maniacally and make roaring noises that always seem to scare off my house guests, and resemble that of an angry dog or a lion. Ive heard that this is the general nature of dinosaurs, but im not quite sure what a dinosaur is. I seem to be turning a deep green though, and am growing spikes down my spine. I think I may be dying, but people on the street say im a dinosaur(whilst running away in fear) is this true?
